Castle Creations CC BEC 10A 6S Switching Regulator
 

I'm in the process of building a Mugen MBX6T with a Castle Creations 1/8 Mamba Monster/Neu-Castle 2200kV concersion. I'll be probably be using 4s 5000 mah or a 5 cell. Do I need this regulator http://www3.towerhobbies.com/cgi-bin...I=CSEM0005&P=K I've installed a Hobbico CS-170 servo and a RX-461 receiver. Thanks

Never hurts and helps protect the ESC. Its cheap insurance.
